ANGLE :BAn Eon JoINING RAILS.

Application filed June 15,

This invention relates to angle bars such as are used for connectin or splicing the ends of railway rails, and provides improvements therein.

5 The exlensionol'thcuse of refrigerator cars on the raihvays, particularly in late years, has brought into prominence theproblcm of corrosion prevention and replacement of anrgle bars used for the connection 01 rails, as aiiected by theuse of such refrigerator cars.

Brine used as the cooling mediumin refrigerator cars, drops therefrom on to the rails and angle bars. This brine has a strong corrosive action on the angle bars and results in an unusually rapid loosening and wear thereof. a v

The present invention provides angle bars which are protcctedagainst corrosion, and which give longer Wear and maintain a tight connection with the rail ends, thereby very much diminishing the maintenance of the railway as regards replacements and tightening of the rail connections. I

An electrodeposit of cadmium has been found-to offer goodprotection'against brine corrosion, and stands up well. against the corrosion encountered on railway .IOitClbQClS. Cadmium plated angle bars have the drawback that the metal is soft and readily wears under the abrasion to which itis subject at the meeting faces with the rail. I According to the present invention. the angle bars. at the point or points where abrasion with the rail takes place, is coated with a coating of a metal which is resistant to corrosion and also hard and resist-ant to abrasion. For this purpose, electrolytic chromium is preferably employed on the surfacessubject to abrasion, protection of theother surfaces against cormium.

An embodiment of the invention is illustrated in the accompanying drawing. 1 3

In said drawing, Figure 1 is a perspective view of anangle bar, the thickness of the coatings being exaggerated and broken away to show the underlying metal.

Fig. 2 is a cross-sectional view showing a rail end and an angle bar on each side of the rail, forming the connection of the rail ends. Referringto said drawing, numeral 10 designi tes an angle bar comprisinga head 11, a foot 12, and a' web 13. The head 11 bears rosion being provided by a coating of cad.

and the foot 12 bears against the flange of the rail. The maximum abrasion oceurs'between the underside of the ball of the rail and the head of the angle bar,-this being due probably to a slight flexibility of the rail, particularly at'its end. I

The head ll of the angle bar is coated with a metal which is corrosion resistant-and of a hardness of the order of steel. The coating is preferably electrolytic chromium, and is indicated on the drawing by numeral 15. The coating of chromium is'elfected by any well known process, being preferably electrolytieally deposited according to the process described in the )atent to Colin G. Fink, No. 1,581,188, dated pril20,1926.

The foot- 12 andweb 13 are preferably coated with cadmium, the cadmium coatingbeing indicated on the drawing by the numeral 17. The cadmium is preferably an electrolytic coating applied according tothe Udylite process or other well known process.

The angle bars, constructed as herein described, are applied to rails in the usual manner, the sides of the angle bars making contact with theends of two abutting rails and drawn together by bolts which pass through the angle bars and the rail ends. The assembly is shown in Fig. 2.

The chromium coated head of the angle bar bears on the underside of the'ball of the rail, and being hard and resistant to corrosionand itlllaSlOD, gives relatively long service w thout requiring replacement. Moreover, by reason of the minimizing of the cor rosion and abrasion, a. tightjoint is maintamed for a relatively long period, thereby economizing in the maintenance of the rail connections. by necessitating tightening at less frequent intervals.

The wear on the foot of the angle bar against the rail is considerablyless than that at the head, so that it is not generally necessary to apply a hard abrasion-resistant coat ing to that part; thougluif desired, the underside of the foot of the angle bar may also be provided with a coating of chromium or equivalent metal. I

The invention may receive other embodiments than that specifically illustrated and described.

What is'claimed is :---v

1. A steel angle bar for joining the ends of rails, said angle bar having-a head-adapted to bear against the underside of the ball of a rail and said head being coated with a coating which is corrosion resistant and of a hardness at least equal to that of the steel of which the angle bar is composed.

2. A steel angle bar for joining the ends of rails, said anglebar having a head adapted to bear against the underside of the ball of a rail and said head being coated Withelectrodeposited chromium.

3. A steel angle bar for joining the ends of rails, having a corrosion resistant coating thereon, said angle bar having a head adapted to bear against the underside of. the ball of a rail, and said head being coated with electrodeposited chromium.

4. A steel angle bar for joining the ends of my name.
